Abstract
In a non-limiting embodiment, a magnetic memory device includes a memory component having a plurality of magnetic storage elements for storing memory data, and one or more sensor components configured to detect a magnetic field external to the memory component. The sensor component outputs a signal to one or more components of the magnetic memory device based on the detected magnetic field. The memory component is configured to be terminated when the signal is above a predetermined threshold value. In some embodiments, a magnetic field is generated in a direction opposite to the direction of the detected external magnetic field when the signal is above the predetermined threshold value.
